Swollen lymph node behind ear? infection or what?

Question

behind my right ear i have a swollen lymph node it isn't to big. i don't feel sick or anything. so what might it be? i just noticed it a few days ago after swimming in freezing water =) at ocean

Answer 1

Very likely nothing to worry about.  Lymph nodes commonly swell up if the body is fighting off a minor infection or virus.  

As a rule you should see a doctor if:

* The node appeared for no apparent reason

* It continues to enlarge

* The node feels hard or fixed

* The swollen node is accompanied by fever, night sweats or unexplained weight loss

* If the node is red, warm and tender

If the node isn't gone in say a week, I'd ask my doctor about it just to be safe.
